Presentation

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

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

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