Presentation

minimal degreeμ(G) = 28
transitive degreeμt(G) = 128

A minimal faithful permutation representation — 7 generators on 28 points:

(5,6,8,9)(7,10,12,11)(14,17)(15,19)(21,22)(23,25)(24,27)(26,28);(5,6)(7,11)(8,9)(10,12)(13,14,16,17)(15,18,19,20)(21,23,24,28)(22,25,27,26);(6,9)(10,11)(14,17)(15,19)(23,28)(25,26);(3,4);(5,6)(7,10)(8,9)(11,12)(13,15)(14,18)(16,19)(17,20)(21,22)(23,26)(24,27)(25,28);(1,2)(3,4);(5,7)(6,10)(8,12)(9,11)(13,14)(15,18)(16,17)(19,20)(21,23)(22,26)(24,28)(25,27)

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