Presentation

minimal degreeμ(G) = 28
transitive degreeμt(G) = 512

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

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

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

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