Presentation

minimal degree	μ(G) = 28
transitive degree	μ_t(G) = 512

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

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