McMullen problem
The McMullen problem is an open problem in discrete geometry named after Peter McMullen.
Statement.
In 1972, McMullen proposed the following problem:
Equivalent formulations.
Equivalent formulations Gale transform.
Using the Gale transform, this problem can be reformulated as:
The number formula_5, formula_1 are connected by the relationships
Equivalent formulations Partition into nearly-disjoint hulls.
Also, by simple geometric observation, it can be reformulated as:
The relation between formula_12 and formula_13 is
Equivalent formulations Projective duality.

Along the way, Smith was named team president in 1976 and played a key role in resolving the club's ownership problem when he helped to convince Dr. John McMullen, a limited partner in Steinbrenner's ownership group, to sell his Yankees' shares and become the owner of the Astros.
However, in a move that shocked baseball, McMullen fired Smith only days after the team's successful 1980 season. McMullen's motive was never fully explained. In fact, some of the Astros
