Presentation

minimal degree	μ(G) = 28
transitive degree	μ_t(G) = 256

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

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