Presentation

minimal degree	μ(G) = 26
transitive degree	μ_t(G) = 512

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

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

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