Presentation

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

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

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

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

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