Presentation

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

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

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