Presentation

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

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

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

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

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