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