Presentation

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

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

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

GAP

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

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