# Use symbolic notation, shown below, for the operations on an equilateral triangle. I = ( 1 2 3 1 2 3 ) , R 120 = ( 1 2 3 2 3 1 ) , R 240 = ( 1 2 3 3 1 2 ) R l = ( 1 2 3 1 3 2 ) , R t = ( 1 2 3 3 2 1 ) , R r = ( 1 2 3 2 1 3 ) R t Δ R r

To determine

To Calculate : the given value using symbolic notation shown for operations on an equilateral triangle - RtΔRr

Explanation

Given information: I=( 123 123),R120=( 123 231),R240=( 123 312)Rl=( 123 132),Rt=( 123 321),Rr=( 123 213)

Formula Used: Use the triangular symmetry group Calculation: Use the triangular symmetry group to find RtÎ”Rr
