Presentation

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

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

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