Using the principal values of the inverse trigonometric functions, the sum of the maximum and the minimum values of $16 \left( \left( \sec ^ { - 1 } x \right) ^ { 2 } + \left( \operatorname { cosec } ^ { - 1 } x \right) ^ { 2 } \right)$ is:
(1) $24 \pi ^ { 2 }$
(2) $22 \pi ^ { 2 }$
(3) $31 \pi ^ { 2 }$
(4) $18 \pi ^ { 2 }$
