This work presents a completely rigorous and self-contained extension of the full apparatus of Meta-Operational Mathematics to the Euler Beta function B and its multi-valued compositional inverse B^-1. The central philosophical principle -- that operations upon operations constitute meta-operations -- is established with complete mathematical precision through a four-level hierarchical framework: Level 0 (elements of a base space), Level 1 (operations as mappings on the base space, now including both unary and binary operations), Level 2 (meta-operations as mappings on operations), and Level 3 (meta-meta-operations acting on meta-operations). Within this framework, the Beta function B and its compositional inverse B^-1 are shown to admit canonical lifts to meta-operations via composition, and these meta-operations interact with one another through composition, pointwise addition, pointwise multiplication, partial differentiation, exponentiation, and logarithm in arbitrarily many iterations -- integer, fractional, real, and complex. A fundamental distinction from both the hyperbolic, elliptic, and Gamma cases is established: the Beta function is essentially a binary operation satisfying the characteristic symmetry B (x, y) =B (y, x) and the difference equation B (x+1, y) =xx+yB (x, y) rather than a unary periodicity or addition formula. This leads to the Beta Symmetry Axiom (Axiom B. 25) and the Beta Difference Axiom (Axiom B. 26), in which the two-dimensional translation group (², +) acts non-trivially with no non-zero kernel, and the intertwining relation T₁, ₀=M䃑䃑䃒 replaces the elliptic quotient group /. The seven fundamental meta-operations generating the whole Beta operad are composition, pointwise addition, pointwise multiplication, first partial differentiation, second partial differentiation, the identity operation, and the Beta function.
