Presentation

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

A minimal faithful permutation representation — 7 generators on 26 points:

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

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

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