## Idea

In type IIA string theory an O4-plane is an orientifold plane (“O-plane”) of dimension $4+1$, hence of the same dimension as D4-branes, but carrying opposite D-brane charge.

## Properties

### Lift to the MO5-plane in M-theory

Under duality between M-theory and type IIA string theory, for KK-compactification along a circle-fiber parallel to an MO5-plane, a plain MO5-plane in M-theory becomes the O4-plane, specifically the $O^- 4$-plane, while an MO5 with an M5-brane on top of it becomes the $O^+ 4$-plane (Gimon 9, Sec. III8,Hanany-Kol 00, Sec. 3.1).
