Presentation

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

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

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

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

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