Presentation

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

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

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