does anyone have good resources to learn the notation? i could figure out basic things like
((λx.x)(λa.a))((λ x . x) (λ a . a))

but got filtered by
(((λf.(λx.(fx)))(λa.a))(λb.b))(((λ f . (λ x . (f x))) (λ a . a)) (λ b . b))

Usually repeated abstraction is notated as just
lam f x. ...
instead of
lam f. lam x. ...
Lambda calculus isn't usually used in practice.
Not sure what you want to use it for.
