F# and the useful infinite Sequence (I think) - So I have seen a few posts done by other F# fans on solving project Euler problems. They looked really interesting and I thought with my limited

F Sharp Programming/Sequences - This is in contrast to lists, where F# computes the value of all elements in a list on Additionally, sequences can represent an infinite number of elements:.

F# - Sequences - F# - Sequences - Sequences, like lists also represent an ordered collection of at once, and for this reason they are used to represent infinite data structures.

F# Friday – The reduce Function – Brad Collins - The result of a reduce operation is always the same type as the elements in the collection. In other words, you can only reduce a collection of type A to a value of type A . You cannot reduce a collection of type A to a value of type B .

Difference between fold and reduce? - Fold takes an explicit initial value for the accumulator while reduce uses the first element of the input list as the initial accumulator value.
