Query: Black hole Skyrmion in a generalized Skyrme model   We study a Skyrme-like model with the Skyrme term and a sixth-order
derivative term as higher-order terms, coupled to gravity and we construct
Schwarzschild black hole Skyrme hair. We find, surprisingly, that the
sixth-order derivative term alone cannot stabilize the black hole hair
solutions; the Skyrme term with a large enough coefficient is a necessity.
