The Type II hidden symmetries are extra symmetries in addition to the inherited symmetries of the differential equations when the number of independent and dependent variables is reduced by a Lie-point symmetry.

## Abstract The complete symmetry group of a 1 + 1 evolution equation has been demonstrated to be represented by the six‐dimensional Lie algebra of point symmetries __sl__(2, __R__) βŠ•~__s__~__W__, where __W__ is the three‐dimensional Heisenberg–Weyl algebra. We construct a complete symmetry group o
