Presentation

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

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

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

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