Presentation

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

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

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

GAP

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

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