Presentation

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

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

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