Presentation

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

A minimal faithful permutation representation — 6 generators on 28 points:

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