Covering blocks and covered blocks
Let [math]N \triangleleft G[/math] with prime [math]p'[/math]-index and let [math]B[/math] be a block of [math]\mathcal{O} G[/math] covering a block [math]b[/math] of [math]\mathcal{O} N[/math].
If [math]b[/math] is in M(32,51,16), then [math]B[/math] is in M(32,51,16) or M(32,51,29.
Projective indecomposable modules
Labelling the simple [math]B[/math]-modules by [math]S_1, \dots, S_{21}[/math], the projective indecomposable modules have Loewy structure as follows:
