We find some lifts to M-theory of orientifold and orbifold planes including the O1, O3 and O5 planes of type IIB and their transformations under SL(2,). The possible discrete torsion variants (or K-theory classes) are explored, and are interpreted as arising from brane intersections with planes. We find new variants of the O0 and of an orbifold line (OF1) and determine their tensions in some cases. A systematic review of orientifolds, M orientifolds, and known M-lifts, with some new clarifications is included together with a discussion of the role of T-duality.

Moduli stabilization from fluxes in a simple IIB orientifold (2002, background): “As discussed in [17] and [18], there are actually three other types of O3-plane, each characterized by the presence of discrete RR and/or NS flux at the orientifold plane.”
Moduli stabilization in chiral type IIB orientifold models with fluxes (2003, background): “At leading order, we will show that the F-flux through 2-cycles can cancel all R-R tadpoles, with chiral fermions and part of the Kähler moduli frozen via a D-term potential.”
Top down approach to 6D SCFTs (2018, background): “[56–58]) one can also engineer the D-type series.”
Heterotic Strings with Torsion (2002, background): “But before we go into this we should first see how the couplings and volumes of the compactified space change under the series of U -duality transformations.”
Fractional M2-branes (2008, background): “A single 5-brane that intersects an orientifold 3-plane in two spatial dimensions will therefore change it from one type on one side to a different type on the other side [25,19] .”
Fixing all moduli in a simple f-theory compactification (2005, background): “This does not change the geometry; it merely corresponds to turning on (torsion) twisted cohomology classes for the field strengths H3 and/or F3 in H 3(IRIP5, Z̃Z), where IRIP5 = S5/ZZ2 surrounds the O3 in Y/ZZ2 [104,60,11].”
A simple class of N = 3 gauge/gravity duals (2008, background): “The i–th of these fivebranes has charges (1, pi), and is extended along 012[37]θi[48]θi[59]θi, where tan(θi) = pi.”
Reading between the lines of four-dimensional gauge theories (2013, unknown): “S̃p(N) theories of [52] (see also [53]).”
