 ly exponentially many in $n$ subalgebras of the $n$-th power. It is known 
 that if this is not the case\, the algebra has few subpowers\, i.e.\, ther
 e is a polynomial $p$ such that there are at most $2^{p(n)}$ subalgebras o
 f the $n$-power. All finite algebras having this property have been charac
 terized in 2009 by Berman\, Idziak\, Markovic\, McKenzie\, Valeriote\, and
  Willard. In the talk\, we will focus on infinite algebras with few subpow
 ers\; in particular we require that we have a finite number of subalgebras
  of powers. These algebras seems to be much rarer than their finite counte
 rparts. We will give a few examples\, and describe how the clasification o
 f the finite algebras generalize to the infinite\, and in particular to al
 gebras that are obtained by taking polymorphisms of countable structures.
