Presentation

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

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

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