For each possible number of solutions between 0 and 256 the rigth columns show how many polynomials in Z_16 over 2 variables of degree up to 2 have that many solutions. The total number of polynomials is 16777216 = 16^6. For example, there are precisely 4 polynomials that have 256 solutions. 0: 2308260 1: 0 2: 0 3: 0 4: 0 5: 0 6: 0 7: 0 8: 3145728 9: 0 10: 0 11: 0 12: 0 13: 0 14: 0 15: 0 16: 6991872 17: 0 18: 0 19: 0 20: 0 21: 0 22: 0 23: 0 24: 2097152 25: 0 26: 0 27: 0 28: 0 29: 0 30: 0 31: 0 32: 1718784 33: 0 34: 0 35: 0 36: 0 37: 0 38: 0 39: 0 40: 0 41: 0 42: 0 43: 0 44: 0 45: 0 46: 0 47: 0 48: 450560 49: 0 50: 0 51: 0 52: 0 53: 0 54: 0 55: 0 56: 0 57: 0 58: 0 59: 0 60: 0 61: 0 62: 0 63: 0 64: 50640 65: 0 66: 0 67: 0 68: 0 69: 0 70: 0 71: 0 72: 0 73: 0 74: 0 75: 0 76: 0 77: 0 78: 0 79: 0 80: 12288 81: 0 82: 0 83: 0 84: 0 85: 0 86: 0 87: 0 88: 0 89: 0 90: 0 91: 0 92: 0 93: 0 94: 0 95: 0 96: 1024 97: 0 98: 0 99: 0 100: 0 101: 0 102: 0 103: 0 104: 0 105: 0 106: 0 107: 0 108: 0 109: 0 110: 0 111: 0 112: 0 113: 0 114: 0 115: 0 116: 0 117: 0 118: 0 119: 0 120: 0 121: 0 122: 0 123: 0 124: 0 125: 0 126: 0 127: 0 128: 888 129: 0 130: 0 131: 0 132: 0 133: 0 134: 0 135: 0 136: 0 137: 0 138: 0 139: 0 140: 0 141: 0 142: 0 143: 0 144: 0 145: 0 146: 0 147: 0 148: 0 149: 0 150: 0 151: 0 152: 0 153: 0 154: 0 155: 0 156: 0 157: 0 158: 0 159: 0 160: 0 161: 0 162: 0 163: 0 164: 0 165: 0 166: 0 167: 0 168: 0 169: 0 170: 0 171: 0 172: 0 173: 0 174: 0 175: 0 176: 0 177: 0 178: 0 179: 0 180: 0 181: 0 182: 0 183: 0 184: 0 185: 0 186: 0 187: 0 188: 0 189: 0 190: 0 191: 0 192: 16 193: 0 194: 0 195: 0 196: 0 197: 0 198: 0 199: 0 200: 0 201: 0 202: 0 203: 0 204: 0 205: 0 206: 0 207: 0 208: 0 209: 0 210: 0 211: 0 212: 0 213: 0 214: 0 215: 0 216: 0 217: 0 218: 0 219: 0 220: 0 221: 0 222: 0 223: 0 224: 0 225: 0 226: 0 227: 0 228: 0 229: 0 230: 0 231: 0 232: 0 233: 0 234: 0 235: 0 236: 0 237: 0 238: 0 239: 0 240: 0 241: 0 242: 0 243: 0 244: 0 245: 0 246: 0 247: 0 248: 0 249: 0 250: 0 251: 0 252: 0 253: 0 254: 0 255: 0 256: 4
