Presentation

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

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

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

GAP

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

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