Presentation

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

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

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

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

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