Presentation

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

A minimal faithful permutation representation — 3 generators on 28 points:

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