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

GAP

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

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