Presentation

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

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

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

GAP

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

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