Presentation

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

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

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