Triplets of Products of Two Distinct Primes

Theorem
The following triplets of consecutive positive integers are the smallest in which each number is the product of $2$ distinct prime numbers:


 * $33, 34, 35$
 * $85, 86, 87$
 * $93, 94, 95$
 * $141, 142, 143$
 * $201, 202, 203$
 * $213, 214, 215$
 * $217, 218, 219$

Proof
Taking each triplet in turn:

It is noted that the triplet:
 * $121, 122, 123$

while consisting of semiprimes, not all of these are the product of $2$ distinct prime numbers, as $121 = 11^2$.
