Presentation

minimal degreeμ(G) = 26
transitive degreeμt(G) = 256

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

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

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