Presentation

minimal degreeμ(G) = 28
transitive degreeμt(G) = 256

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

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

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