Presentation

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

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

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