Presentation

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

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

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

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