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

GAP

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

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