Presentation

minimal degreeμ(G) = 26
transitive degreeμt(G) = 128

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

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

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