To describe present a set of results giving the 2 modular character table of Conway's first group, suitable for inclusion in the forthcoming Atlas of Brauer Characters Part 2.
Conway's first group is described in [Conway]. Throughout this
paper, it will be denoted
At the point of starting on the problem, some small representations of
The results are as complete as they can be subject to condensation. There are eight results which are condensation only. There are a further three results which combine condensation and character theory to yield an existence proof (the character theory implies a decomposition which the condensation proves to be the most that can occur). The remaining fifteen irreducibles have all been constructed and their indicators computed, and for seven of these of indicator plus the orthogonal group has also been determined. Two further indicators are known, as two of the three ireducibles proved by condensation constitute a complex conjugate pair.

The tensor condensations in the above section have resulted in some
very large matrices, which take a long time to produce and are hard to
reduce. For example, the condensed tensor product
The degree of the condensed matrices is roughly equal to the uncondensed degree divided by the condensation subgroup order. So why don't we just pick a larger condensation subgroup? The answer is that the larger subgroups (of McL at least) are unfaithful, ie there is an irreducible representation which condeses to zero. In this case the culprit is 1496.
But, if we are merely interested in the multiplicities, and we had an alternative means to determine the missing multiplicities, we could then make use of a larger condensation subgroup. For example, the full Sylow 3 subgroup of McL is faithful on every representation except 1496, and would lead to condensed matrices of degree around 160000.
Condensation relies on looking at the subspace fixed by the condensation subgroup, under the action of a suitably smaller algebra. If M is an irreducible of the group algebra kG, and e the central idempotent formed from the sum over the elements of the condensation subgroup H, then our condensation space is Me acted on by ekGe. But Me is just the subspace in the direct sum decomposition of M as a kH module all of whose summands are isomorphic to the trivial representation.
So, what would happen if we chose a different central idempotent f? The first obvious consequence is that we no longer have control of the multiplicity of the trivial representation. But, if we also condensed using the original e, we could regain this information. In terms of our original example, we would gain a factor of nine, only to lose a factor of two on the matrix construction. But the reduction process is cubic in the degree, so here we would gain twenty seven divided by two.
However, if we choose an idempotent associated with a non-linear character, we could well lose any possible advantage due to higher multiplicity of the irreducible direct summand, coupled with large degree. So, initially I'd prefer to consider only non-trivial linear characters. A further complication is that condensing over GF(2), the trivial character is the only linear character. So, we might also have to consider moving to GF(4) (which for the Sylow 3 subgroup would give a number of non-trivial linear characters). We'd still get a factor of about two (or possibly better, since only the non-trivial character condensation needs to be done in the field extension) on overall space requirements, and a factor around six on reduction speed. With larger odd order subgroups greater savings might be made.
The next question that needs to be answered is how do we make these non-trivial character condensations? I think that for permutation condensations, we need to compute the relevant idempotent (I believe there are formulae from Schur for these). For tensor condensation, I think we need a permutation of the symmetry basis for the right hand component. Essentially, instead of taking the basis in the order of the duals of the irreducbles of the condensation subgroup, I believe we now need dual ⊗ λ, where λ is our non-trivial linear character. Note that in this case, the tensor product is irreducible (another advantage of sticking to linear characters).
Food for thought!
