Presentation

minimal degree	μ(G) = 28
transitive degree	μ_t(G) = 128

A minimal faithful permutation representation — 4 generators on 28 points:

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