Presentation

minimal degree	μ(G) = 26
transitive degree	μ_t(G) = 256

A minimal faithful permutation representation — 6 generators on 26 points:

(4,6)(11,12)(13,17)(14,16)(15,18)(19,20,22,24)(21,23,25,26);(4,6)(8,10)(19,21,22,25)(20,23,24,26);(11,12,14,16)(13,15,18,17)(19,21)(20,23)(22,25)(24,26);(7,8)(9,10)(11,12)(13,15)(14,16)(17,18)(19,21)(20,23)(22,25)(24,26);(3,4)(5,6)(11,13)(12,15)(14,18)(16,17)(19,20)(21,23)(22,24)(25,26);(1,2)

GAP

Past the SmallGroups library coverage — no SmallGroups id. Construct it from a minimal faithful permutation representation:

gap> G := Group((4,6)(11,12)(13,17)(14,16)(15,18)(19,20,22,24)(21,23,25,26), (4,6)(8,10)(19,21,22,25)(20,23,24,26), (11,12,14,16)(13,15,18,17)(19,21)(20,23)(22,25)(24,26), (7,8)(9,10)(11,12)(13,15)(14,16)(17,18)(19,21)(20,23)(22,25)(24,26), (3,4)(5,6)(11,13)(12,15)(14,18)(16,17)(19,20)(21,23)(22,24)(25,26), (1,2));
