Presentation

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

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

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

GAP

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

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