dc.abstract.en \lambda υ is an extension of the \lambda -calculus which internalises the calculus of substitutions. In the current paper, we investigate the combinatorial properties of \lambda υ focusing on the quantitative aspects of substitution resolution. We exhibit an unexpected correspondence between the counting sequence for \lambda υ-terms and famous Catalan numbers. As a by-product, we establish effective sampling schemes for random \lambda υ-terms. We show that typical \lambda υ-terms represent, in a strong sense, non-strict computations in the classic \lambda -calculus. Moreover, typically almost all substitutions are in fact suspended, i.e. unevaluated, under closures. Consequently, we argue that \lambda υ is an intrinsically non-strict calculus of explicit substitutions. Finally, we investigate the distribution of various redexes governing the substitution resolution in \lambda υ and investigate the quantitative contribution of various substitution primitives. pl
