  Recently, Williams [1] and then Yao, Xia and Jin [2] discovered explicit formulas for the coefficients of the Fourier series expansions of a class of eta quotients. Williams expressed all coefficients of 126 eta quotients in terms of 
  <img src="Edit_2f7d2589-0418-42d6-8c22-98b51dad532d.bmp" alt="" /> and 
  <img src="Edit_195a6f5f-e115-4d16-95b3-c78596385933.bmp" alt="" /> and Yao, Xia and Jin, following the method of proof of Williams, expressed only even coefficients of 104 eta quotients in terms of 
  <img src="Edit_9d5185f0-655a-4fec-93d3-9960d390287a.bmp" alt="" /> and 
  <img src="Edit_9ef39348-eb43-4e0b-ba39-a28a78311902.bmp" alt="" /> . Here, by using the method of proof of Williams, we will express the even Fourier coefficients of 360 eta quotients i.e., the Fourier coefficients of the sum, f(q) + f(?q), of 360 eta quotients in terms of 
  <img src="Edit_03161f2b-68c1-4dc9-a70a-5bb846aee890.bmp" alt="" /> and
