In detail, we define: + charsimple G == G is characteristically simple (it has no nontrivial + characteristic subgroups, and is nontrivial) + 'Phi(G) == the Frattini subgroup of G, i.e., the intersection of + all its maximal proper subgroups. + 'F(G) == the Fitting subgroup of G, i.e., the largest normal + nilpotent subgroup of G (defined as the (direct) + product of all the p-cores of G). + critical C G == C is a critical subgroup of G: C is characteristic + (but not functorial) in G, the center of C contains + both its Frattini subgroup and the commutator [G, C], + and is equal to the centraliser of C in G. The + Thompson_critical theorem provides critical subgroups + for p-groups; we also show that in this case the + centraliser of C in Aut G is a p-group as well. + special G == G is a special group: its center, Frattini, and + derived sugroups coincide (we follow Aschbacher in + not considering nontrivial elementary abelian groups + as special); we show that a p-group factors under + coprime action into special groups (Aschbacher 24.7). + extraspecial G == G is a special group whose center has prime order + (hence G is non-abelian). + 'SCN(G) == the set of self-centralising normal abelian subgroups + of G (the A <| G such that 'C_G(A) = A). + 'SCN_n(G) == the subset of 'SCN(G) containing all groups with rank + at least n (i.e., A \in 'SCN(G) and 'm(A) >= n). +</div> +<div class="code">
