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