  Catalan's constant and the lemniscate constants have been important
mathematical constants of interest to the mathematical society, yet various
properties are unknown. An important property of significant mathematical
constants is whether they are normal numbers. This paper evaluates the
normality of decimal and hexadecimal representations of current world record
computations of digits for the Catalan's constant (600,000,000,100 decimal
digits and 498,289,214,317 hexadecimal digits) and the arc length of a
lemniscate with $a=1$ (600,000,000,000 decimal digits and 498,289,214,234
hexadecimal digits). All analyzed frequencies are persistent to the conjecture
of Catalan's constant and the arc length of a lemniscate with $a=1$ being a
normal number in bases 10 and 16.
