Presentation

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

A minimal faithful permutation representation — 5 generators on 28 points:

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