Presentation

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

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

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