Presentation

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

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

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

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