27495 is a member of OEIS A349773: numbers that start a run of four consecutive triangular numbers with four distinct prime factors (these are shown below).

The sequence can be generated as follows:

INPUT

target=27495

L=[]

T=[n*(n+1)/2 for n in [1..250]]

for i in range(len(T)-3):

  OK=1

  for x in [0..3]:

    if len(prime_factors(T[i+x])) != 4:

      OK=0

      break

  if OK==1:

    L.append(T[i])

    if T[i]==target:

      for x in [0..3]:

        print(T[i+x],"=",factor(T[i+x]))

print()

print(L)

OUTPUT

27495 = 3^2 * 5 * 13 * 47

27730 = 2 * 5 * 47 * 59

27966 = 2 * 3 * 59 * 79

28203 = 3 * 7 * 17 * 79
