Presentation

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

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

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