Presentation

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

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

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