one of the dualities in string theory: between type I string theory and heterotic string theory

(…)

Properties

Gauge group

For type I string theory on flat target spacetime orientifolds 9,1\mathbb{R}^{9,1} RR-field tadpole cancellation requires 32 D-branes to cancel the O-plane charge of -32 (here).

Under the duality between type I and heterotic string theory this translates to the semi-spin gauge group SemiSpin(32) of heterotic string theory.
