Presentation

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

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

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