Query: Composition factors of 2-parts spin representations of symmetric groups   Given an odd prime $p$, we identify composition factors of the reduction
modulo $p$ of spin irreducible representations of the covering groups of
symmetric groups indexed by partitions with 2 parts and find some decomposition
numbers.
