Presentation

minimal degreeμ(G) = 28
transitive degreeμt(G) = 64

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

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

Past the SmallGroups library coverage — no SmallGroups id. Construct it from its polycyclic presentation:
