Presentation

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

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

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

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

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