Presentation

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

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

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