Presentation

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

A minimal faithful permutation representation — 7 generators on 26 points:

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

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