Presentation

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

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

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