Now we're cooking with gas! (Double digit thermo sudoku)

(Published on 5. September 2022, 23:47 by bradygilg)

Somebody has turned up the heat on these thermometers! Instead of capping out at 9, the entries in this sudoku go up to 100! You can play this puzzle on Penpa here.
Rules: Place 64 distinct integers from 0 to 100 (inclusive) into the grid.
  • All entries must be different.
  • In each row and column, all pairs of numbers must have a difference of 10 or greater. For example, 25 and 34 cannot appear in the same row or column together, because 34-25=9.
  • Cells along a thermometer must form an increasing arithmetic sequence, i.e. adjacent pairs of numbers on the thermometer must all increase by a constant step size. The step sizes may be different for different thermometers. For example, 5-20-35-50-65 is a valid thermometer with step size 15, but 5-20-30-43-65 is an invalid thermometer because the step size is not consistent.
I suggest using Penpa's Number-1/4 feature to note the minimum and maximum values for each cell. A walkthrough solution of this puzzle is available here.

Solution code: The solution code is the first (top) row of integers written from left to right with no spaces in between. Single digit entries do not have a leading zero.
