Presentation

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

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

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

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