In this paper, which is based on the first part of the author's PhD thesis, we review the statistics of the open string sector in T 6 /(ℤ 2 × ℤ 2 ) orientifold compactifications of type IIA. After an introduction to the orientifold setup we discuss the two different techniques that have been developed, using either a saddle point approximation or a direct computer based method. We explain the two approaches by means of eight‐ and six‐dimensional toy models and present the results for the four‐dimensional models in detail. Special emphasis is placed on models containing phenomenologically interesting gauge groups, in particular those containing a standard model, Pati‐Salam or SU(5) part.
